Analysis

The pilot stated that, during an IFR cargo operation, the aircraft had a total loss of electrical power. He descended to VFR flight conditions and elected to attempt an off-airport landing in an open field. He was unable to extend the landing gear manually so decided to land gear up. The acft slid for considerable distance in the field, then struck a rock fence. Post accident investigation revealed a broken wire on an electrical cannon plug, located on the right engine firewall, that had shorted out.
